Technical challenges still remain, however, mainly including interference, security and mobility management, intercepting wide deployment and adoption from mobile operators and end users. This paper describes a novel handover decision policy for the two-tier LTE network, towards reducing power transmissions at the mobile terminal side. The proposed policy is LTE backward-compatible, as it can be employed by suitably adapting the handover hysteresis margin with respect to a prescribed SINR target and standard LTE measurements. Simulation results reveal that compared to the widely-adopted strongest cell policy, the proposed policy can greatly reduce the power consumption at the LTE mobile terminals, and lower the interference network-wide. 5 pp. LOMv1.0 creator LOMv1.0 publisher LOMv1.0 Scientific Coordinator LOMv1.0 Project Executing Organisation 2012-06 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text LTE; femtocells Handover decision policy Energy efficiency Power consumption Interference management 326242 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/3325/2/3325_1.15_%ce%94%ce%97%ce%9c_30_6_12.pdf URI http://hdl.handle.net/10795/3325 LOMv1.0creator 2016-05-23T09:09:52Z LOMv1.0validator 2016-05-23T09:09:52Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
